Singer John Mayer spotted wearing a Audemars Piguet

John Mayer was recently spotted on the wrist wearing the Audemars Piguet Royal Oak Offshore Diver in turquoise blue, reference 15710ST — a piece that sits at the intersection of functional dive tool and chromatic statement. Mayer, who regularly cycles through serious references from Patek Philippe, independent brands, and AP alike, chose a watch here that rewards closer inspection far beyond its eye-catching colour.

The Royal Oak Offshore Diver 15710ST measures 42mm in stainless steel and carries a water resistance rating of 300 metres, supported by a unidirectional rotating bezel in matching turquoise ceramic. Inside sits Audemars Piguet's Calibre 3120 — an entirely in-house automatic movement with a 60-hour power reserve, 21,600 vph beat rate, and a 280-component architecture that collectors have long respected for its finishing quality relative to its price point. The integrated rubber strap echoes the dial's turquoise tone, giving the piece a cohesive, almost monochromatic sportiness that distinguishes it from the broader Offshore family.

The 'Funky Colours' designation refers to a run of Offshore Diver editions released across multiple years featuring vivid dial and bezel combinations — orange, green, blue, and this particular turquoise — that drew a younger, more style-conscious buyer to a reference that had previously struggled to differentiate itself from the larger Offshore chronograph. In doing so, AP created genuine secondary-market heat around what had been a quietly underappreciated ref. The turquoise variant is broadly considered among the most desirable of the colour series.

Mayer's horological taste is well-documented and genuinely sophisticated. He has worn and discussed references including complicated Pateks, early AP Royal Oaks, and a range of independent pieces in public-facing settings, demonstrating that his collecting habits are driven by knowledge rather than visibility. His choice of the 15710ST in turquoise reads as deliberate — a steel sport watch with colour personality that holds its own among far pricier company.

On the market, the Royal Oak Offshore Diver 15710ST in turquoise carries a UK list price of approximately £16,800, translating to roughly $21,000 USD at retail. On the grey market, strong demand for the 'Funky Colours' variants has pushed prices noticeably above retail, with clean examples regularly trading between $24,000 and $28,000 USD depending on condition and provenance.
